Letters Patent No. 90,511, dated May 25, 1869.

The Schedule referred to in these Letters Patent and maki'ng part 0f the Bm.

To all whom it 'may concern:

Be it known that I, DAVID DoNALDs, of the city and State of New York, have invented and made a new and useful Improvement in Sad-Irons; and Ido hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specication, wherein- Figure 1 is a vertical transverse section .of the iron and handle; v

Figure 2 is a sectional plan below the line :t

Figure 3 is au inverted plan of the handle; and

Figure 4 is a plan of the iron, the handle being removed.

Similar letters denote the same parts.

` This invention is for facilitating the separation of the handle and the iron, so that the latter may be left to heat upon the stove, while theformer remains cool, or is connected with another similarly-formed flat-iron, the connection being the subject of my invention, the same consisting in a screw and wheel-shaped head, combined with a clasping-jaw on'the handle, aud a T-shaped rib on the flat-iron.

By this construction the parts can be released by a very small turn of the screw, or secured together with great firmness, after .the jaw has been slipped over the rib, by a slight turn'of the screw, and the varying expansion or contraction by the heat has no effect to injure the parts or loosen the connection.

In the drawinga represents the flat-iron, of usual or desired size or shape, upon thetop of which is cast a T-shaped lug, b, forming a longitudinal rib, with a stop at one end.

The wooden handle c is between the metal portion, d, ofthe handle, and l e is a jaw, formed to slide freely over the rib b.

f is-a shield, to protect the hand from radiated heat.

g is a screw, passing through the handle centrally of the jaw e, and having a wheel-head, lt, either above or below the shield f. I have shown the same as below this shield. v y

The edges of this wheel are formed with indentation s, or depressions between projecting spurs, so that the thumb or linger can be applied to the said wheel, to either loosen or tighten the screw g, and either clamp or release the hold ofthe same, and allow the handle and jaw to be slipped oli' the iron, or firmly connect the parts together.

Expansion or contraction under varying changes of temperature will have but little effect on the clamping of the rib, as the screw itself expands in the same direction as the sides of the jaw.

What Il claim, and desire to secure by Letters Pat- The screw g and wheel vl1., in combination with the jaw e, handle c, rib b, and ironic, the parts being constructed as and for the purposes specitied.

In witness whereof', I have hereunto set my signature, this 29th day of April, A. D. 1869.

Witnesses: DAVID DONALDS.
